Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses, that propagate as waves outward from their source at the speed of light. They were proposed by Henri Poincaré in 1905[1] and subsequently predicted in 1916[2][3] by Albert Einstein on the basis of his general theory of relativity.[4][5] Gravitational waves transport energy as gravitational radiation, a form of radiant energy similar to electromagnetic radiation.[6] Newton's law of universal gravitation, part of classical mechanics, does not provide for their existence, since that law is predicated on the assumption that physical interactions propagate instantaneously (at infinite speed) – showing one of the ways the methods of classical physics are unable to explain phenomena associated with relativity.
